Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Resistance exercise intervention: After 12 weeks of usual care and 1 week gap (testing period), participants proceed to 12 week intradialytic resistance training intervention conducted 3 times per week for approximately 30 minutes per session encompassing full body weight training. Moderate to high intensity, progressive resistance training (free weights, elastic tubings and machine) will be administered by an exercise physiologist. The training session will be conducted on an individual basis. A generic set of exercises will be prescribed and progressed according to individual's rating of perceived exertion.

Outcomes
Primary outcome [1] 287069 0
A marker of arterial stiffness, brachial-ankle pulse wave velocity (metre per second) will be measured by applanation tonometry using the SphygmoCor System and Program (AtCor Medical Pty, Sydney, Australia)
Timepoint [1] 287069 0
Baseline (Week 0), Post-usual care (Week 13) and Post-intervention (Week 26)
Primary outcome [2] 287070 0
A marker of arterial stiffness, augmentation index (unit) will be measured by applanation tonometry using the SphygmoCor System and Program (AtCor Medical Pty, Sydney, Australia)
Timepoint [2] 287070 0
Baseline (Week 0), Post-usual care (Week 13) and Post-intervention (Week 26)
Secondary outcome [1] 297309 0
Haematological markers: full blood count, endothelial progenitor cells, C-reactive protein, blood lipids.
Timepoint [1] 297309 0
Baseline (Week 0), Post-usual care (Week 13) and Post-intervention (Week 26)
Secondary outcome [2] 297310 0
Muscular strength: To assess upper body strength, maximal handgrip strength of each arm using a handgrip dynamometer is measured. The highest score out of 3 trials will be measured. To assess lower body strength, 10 repetition maximum (the heaviest weight that can be lifted for only 10 repetitions) of each of the knee extensor and knee flexor will be measured.
Timepoint [2] 297310 0
Baseline (Week 0), Post-usual care (Week 13) and Post-intervention (Week 26)
Secondary outcome [3] 297311 0
Physical function assessed by the six minute walk test. Maximum distance walked in six minutes along a circuit is measured.
Timepoint [3] 297311 0
Baseline (Week 0), Post-usual care (Week 13) and Post-intervention (Week 26)
Secondary outcome [4] 297312 0
Depression level assessed by Geriatric Depression Scale (GDS), with scores more than 9/30 considered as possible depression.

Baseline (Week 0), Post-usual care (Week 13) and Post-intervention (Week 26)
Secondary outcome [5] 297313 0
Medical Outcomes Trust Short-Form 36 will be used to evaluate changes in eight domains of health-related quality of life, including physical functioning.
Timepoint [5] 297313 0
Baseline (Week 0), Post-usual care (Week 13) and Post-intervention (Week 26)
Secondary outcome [6] 297314 0
